MongoDB Senior Software Engineer interview questions

Process was: Recruiter screening, Phone Screen, 5 Virtual Onsite. The whole process took a long time. I loved each interviewer, they were really friendly, nice and passionate with their work. The interview questions were unique and on the harder side but well organized.

Slow moving, didn't seem to have regard for my time (showed up late, clearly weren't prepared with my resume in front of them, etc). Overall felt a lack of care for the process, which was a red flag.
